Reading things like absolute Batman is better because it's neat and there is no need to read 80+ of story that convoluted between what's cannon and what's not.
I'd rather reading comic about obscure superhero that's have very nice story. Because they are niche and unpopular their story may or may not be more compact and better. The popular one is fun too, but because the writer were ever changing the character core always shaky.
